DUMP-WAGON.

Specification of Letters Patent.

Patented June 30, 1908.

Application led October 9, 1907. Serial No. 396,686.

y improvements in dumping wagons and more particularly to dumping wagons of that type which include bottom sections mounted for swinging movement. p

In connection with a dumping wagon of the above general type the inventionaims as a primary object to provide novel means for effecting a swinging movement of the displaceable bottom sections.

The invention aims as a further object to provide novel means for locking the bottom sections normally against swinging movement.

The invention aims as a further object to provide details of structure and assemblage whereby binding of the movable parts, ordinarily due to lodgment of particles of the load, is effectively prevented.

The invention 'finally aims to provide a novel construction, combination and arrangement of parts, the details of which will appear in the course of the following description in which reference is had to the accompanying drawings, forming a part of this specification, like characters of reference designating similar parts, throughout the several views, wherein Figure 1v is a side elevation of a dumping wagon constructed in accordance with the presentinvention, Fig. 2 is a bottom plan view thereof, Fig. 3 is a front elevation thereof, Fig. 4 is a transverse sectional view thereof, and Fig. 5 is a detailed bottom plan view of the locking device for holding the bottom sections against swinging movement, under the weight of the load.

In the accompanying drawings, the wagon body, designated generally by the numeral 1 is shown as of rectangular box-like form and includes, a front end wall 2, side walls 3, and a rear end wall 4, the end walls 2 and 4 being preferably shaped so as to afford ahopper bottom. Transverse bars 5 are secured to the under faces of the walls 3 adjacent to the ends of the latter and the bars 5 conjointly support a longitudinal bar 6 which together with the swinging sections 8, (hereinafter termed doors for the purposes of this specification) constitute the bottom of the body 1.

The bars 5 are constructed as bearings for longitudinal rock shafts 9 and 10 which are secured to the respective doors S by cleats 11 and which have laterally projecting arms 12 bearing against the under surfaces of said doors and constituting reinforcements therefor. The shaft 9 is of greater length than the shaft 10 and at its front end has a depending arm 13. The shaft 10 at its front end has a similar arm 14 and the door rotating means com rises a manual o eratinfT lever and o erative connections between said lever and the arms 13 and 14.

The manual operating lever is designated by the numeral 15 and is pivoted at its lower end as at 16 to a transverse bar 17 connecting the front ends of the side walls 3. A lever 18 is pivoted between its ends as at 19 to the bar 17, one end of the lever 1S being bent recurvately as at 20 and constituting a bill embracing the lever 15 above the ivot of the latter, and the other end of the ever 18 being pivoted to a transverse link 21 whichhas pivotal connection with the arm 13 of the shaft 9. Secured to the part 17 is a bearing 22 for a rock-shaft 23, formed at its front end with a depending arm 24 and at its rear end with an u standing arm 25. The arm 24 is pivoted to t ie link 21 and the arm 25 is pivoted to a link 26 which latter has pivotal connection with the arm 14 of the shaft 10. The lever 15 has its movement in either direction limitedby the ends of a retaining strap 27 secured to the front wall 2.

The locking means for the doors 8 consists essentially of an axially slidable rod 2S provided at desired intervals with collars 29 having at opposite points ears 30. Curved latch members 31, supported by and working through staples 31 secured to the underface of the bar 6, are pivoted to the ears 30 and are designed to engage the underface of the doors S and support said doors in position to close the bottom of the wagon. It will be apparent that forward movement of the rod 2S will result in moving the members 31 from beneath the doors 8 and that rearward movement of the rod 28 will result in engaging said latch members beneath said doors. Such forward and rearward movement of the rod 28 is effected by means of a lever 32 having its handle portion 33 disposed at one side of the body 1 and limited in its movement in either direction by the ends of a retaining strap 34 secured to the adjacent wall3 llh eH lever 32, comprehends in addition to the handle portion 33 a horizontally oset portion 35 journaled in a bearing 36 secured to the upper face of the bar 17, the portion having a depending arm 37 which is pivoted to the front end of the rod 28.

In use, the latch members 31 are disengaged from the doors 8 in the manner described by proper movement of the lever 32 and the lever 15 is then moved in the direction of the arrow as shown in Fig. 3. Such movement of the lever 15 results in rocking the shafts 9 and 10 through the medium of the connections set forth, the doors 8 u on operative movement of the shafts 9 andD 10 moving away from one another and from the bar 6 with which they coperate in closing the bottom of the body 1. It is to be understood that the downward swinging movement of the doors 8 upon proper movement of the lever 15 is due tothe combined weight of said doors and the load superincumbent thereupon. Vhen restoring the doors to closed position, the lever 15 is moved in an opposite direction and engages the curved bill 2O of the lever 18, thus effecting a positive movement of said lever 18 and consequently of the adjunctive elements directly and indirectly connected therewith.

In order to prevent the load particles from having lodgment in the various joints and i interstices, the shafts 9 and 10 are arranged at slight distances from the outer side edges of the doors 8. Longitudinal cleats 38 having inclined upper faces are secured to the inner faces of the side walls 3 adjacent the lower edges of the latter, the cleats 38 hav- 39Vto permit of the pivotal movement of the projecting outer edge portions of the doors 8 during the swinging operations of the latter in either direction. The bar 6 likewise has inclined or beveled faces 40 at each side thereof to facilitate the complete discharge of the load articles.

What I c aim is r1. A dumping wagon including side walls, transverse bars connecting the same, a longitudinal bar supported by said transverse bars, doors mounted for swinging movement on each side of said longitudinal bar, means either direction, collars carried by said rod, latch members ivoted at opposite sides of said collars andp engaging beneath said respective doors and guic es for said latch members, secured to said longitudinal bar.
